Cylinder sizes are expressed in terms of extin- guishing agent capacity (i.e., the PCL-300 uses 3.0 gallons (11.4 L) of extinguishing agent). The cylinder is manufactured, ► tested, and meets DOT requirements. Cylinders come pre- filk!d with extinguishing agent and are charged with dry nitro- gen to a pressure of 225 psig @ 70° F (15.5 bar@ 21 °C).

However, before attempting any installation, it is necessary to attend a Factory Certification Training Class and become Certified to design the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. The chapter is divided into three (3) sections: Nozzle Coverage and Placement • Piping Limitations • Detector Requirements Each of these sections must be completed before attempting any installation. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appli- ance protection. Duct Protection It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. ►All duct protection is UL listed without limitation of maximum duct length (unlimited length). This includes all varieties of ductworks both horizontal and vertical including ducts that run at angles to the horizontal and ducts with directional ►bends. Duct protection requires that a nozzle be positioned to ► discharge into the duct. Two nozzles are available for duct protection. The Model IL Nozzle, Part No. 551026, is a one (1) flow nozzle. A single IL nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 50 in. (127 cm), with the diagonal being a maximum of 18 314 in. (47.6 cm). It can also protect a round duct with a maximum diameter of 16 in. (40.6 cm). The Model 2D duct nozzle, Part No. 551038, is a two (2) flow nozzle. A single 2D nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of ► 100 in. (254 cm), with the diagonal being a maximum of ► 37 3/8 in. (94.9 cm). It can also protect a round duct with a maximum diameter of 31 7/8 in. (81 cm). When two (2) 2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided into two equal symmetrical areas. The nozzle must then be installed on the centerline of the area it protects and aimed directly into the duct opening. The nozzle(s) must be installed on the centerline of the duct, with the tip located Oto 6 in. (15.2 cm) into the opening, and aimed directly into the duct opening. See Figure 3 .. 1a. ► In installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 6 in. (15.2 cm) maximum, to a point just beyond the damper assembly that will not interfere with the damper. Exceeding the maximum of 6 in. (15.2 cm) in this way will not void the ► UL listing of the system. • ILOR20 NOZZLE o-6 IN. INTO DUCT Figure 3-1 a. PN551274(3) f w ! ULEX 3830 August 1, 2005 • Transition Ducts -The protection of non-standard ducts should be reviewed by the authority having jurisdiction. PYRO-CHEM KITCHEN KNIGHT II recommends that transi- tion ducts be protected as follows: a. Transition ducts -larger to smaller In cases where the ducUplenum inter1ace opening is larger than the final exhaust duct, measure the perime- ter/diameter of the duct halfway between the largest and smallest section (or the average perimeter/diame- ter). The nozzle is to be located within 0-6 in. (15.2 cm) of the duct/plenum inter1ace (not at the point where the measurement was taken), centered under the final c. Multiple risers Chapter 3 -System Design Page 3-3 REV. 2 In cases of multiple rises, each riser is protected as an ► individual duct. See Figura 3-1e. DUCT DD ► exhaust duct opening. See Figure 3-1c. ► Figure 3-1e ► ► ► PERIMETER-----',----~ MEASUREMENT Figure 3-1c. b. Transition ducts -smaller to larger 1/2WAY INTO TRANSITION In cases where the ducUplenum intelface opening is smaller than the final exhaust duct, measure the perimeter/diameter of the final exhaust duct. The nozzle(s) is to be located within 0-6 in. (15.2 cm) of the duct/plenum intelface, centered in the opening. See Figure 3-1d. PERIMETER- MEASUREMENT Figure 3·1d Electrostatic Preclpltator -Ducts utilizing electrostatic precipitators must be protected above and below the unit. Standard duct nozzles are used in this application. See ► Figure 3-11. 2D NOZZLE ~-PRECIPITATOR PLENUM 2D NOZZLE 006176PC ► Figure 3-11 ► Plenum Protection The Model 1H nozzle, Part No. 551029, is a one (1) flow nozzle used for plenum protection. A single 1 H nozzle can protect a plenum (with single or V-bank filters) 10 ft. (3.1 m) long by 4 ft. (1.2 m) wide. Dividing the length into sections equal to or less than 10 ft. (3.1 m) in length and positioning a nozzle at the start of each section can be done to protect longer plenums. PN551274(2) ULEX 3830 April 1, 2004 • ■ 5. Large Wok (Greater than 24 in. to 30 in.
